What is the purpose of securely connecting members of support systems?

The purpose of securely connecting members of support systems is fundamentally about safety and stability. When components of a support system are securely connected, it minimizes the risk of sliding, falling, or experiencing other predictable failures during operation. This ensures the integrity of the entire system, enabling it to withstand the forces and stresses it may encounter, especially in the context of heavy machinery like excavators.

A strong, secure connection is critical when dealing with loads, as any failure in the connection can lead to catastrophic results, potentially causing accidents or injuries. Ensuring that members are tightly connected helps maintain the system's structural integrity, which is paramount in construction and excavation environments where safety is a top priority.

Other options may address various aspects of operational efficiency or usability, but they do not prioritize the core requirement of ensuring the safety and reliability of the support systems.
